To all whom iii-may concern:

Be it known that l, Eannns'r L. JACKSON, a citizen of the United States,residing at Columbus, in the county of Muscogee and State of Georgia,have invented certain new and useful Improvements in Attachments forSpeeder Stop-Motions; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to attachments for Speeders and the like, and hasfor an object to provide means for cOnJinuing the action of the traverseand the bobbin-winding apparatus after the breaking of the cone belt anduntil the machinery has been brought to a stop by some form of automaticstop device.

A further object of the invention is to provide a device especially,though not eX- clusively, adapted for operation in conjunction with thestopping device disclosed in application Serial No. 728,174, filedOctober 28, 1912.

With the use of any form of automatic stop mechanism as disclosed insaid applica tion orotherwise the momentum of the machine after the conebelt breaks causes the spinning and feeding apparatus to continue tomove for a limited time, whereas the winding stops. This causes-atangling of the thread. The use of the automatic stop device eliminatesa large amount of such tang-ling, but even when used with an automaticstop device some tangling occurs which it is desirable to avoid.

The present invention embodies means for operating in conjunction withthe cone drive normally out of gear and inoperative and adapted to bethrown into gear and operate only when the lower cone drops, taking upapproximately the speed of the lower cone and continuing to operate thewinding mechanism until the machine comes to a full stop.

A further object of the invention is to provide an automatic clutcharrangement adapted to be thrown into engagement by the dropping of thebottom cone, provided with shafts normally geared into the top coneshaft and into the winding drive shaft but driven normally independentlyfrom such shafts with the clutches out of engagement.

A further object of the invention is to provide such a connecting meanshaving a plurality of speeds driven by separately intergearcd gearings,with means for shifting at each reciprocation of the cone rack.

With these and other objects in view the invention consists in certainnovel features of construction, combination and arrangement of partswill be hereinafter more fully described and claimed.

In the drawings Figure 1 is a fragmentary conventional view of the conemechanism with the improved attachmentconnected therewith.

Fig. 2 is a view of the clutch mechanism with one part of the housingremoved.

Like characters of reference designate corresponding parts throughoutthe several views.

The improved attachment which forms the subject-matter of thisapplication is adapted to be associated with a speeder of the usual andordinary type embodying a top cone 10 and bottom cone 11 as shown Fig.1., the former being driven by its drive-shaft 12, and the latterdriving the winding shaft 13 through any approved connecting means thebelt 1%.. The bottom cone is driven from the top cone by the usual andordinary cone belt 15 which in. turn is shifted by the cone rack 16. Theforegoing mechanism is that found upon the usual and ordinary speederand forms no part of the present invention.

At some conven ent point intermediate the cones the gear housing 17 issecured, having a shaft 18 carrying a bevel gear 19 intergeared with thebevel gear 20 on the top cone shaft 12.

The housing 17 also journals a shaft'21 caryin a bevel gear 22 inter'eared with the bevel gear 23 on the winding drive-shaft 13.

Under normal conditions the shaft 18 is driven from the shaft 12 and theshaft 21 is driven from the shaft 13. with no interengagement within thehousing 17 preventing the free and independent rotation of such shafts.

Within the housing, however, the shaft 18 is provided with a clutchmember 24 splined thereon, and movable longitudinally thereof intoengagement with the clutch face 25 integrally or rigidly connected withthe gear 26 mounted normally free to rotate upon the shaft 18. The shaft21 also carries a similar clutch member 27 splined and slidably movablethereon, adapted to interengage with the clutch face 28 of the gear 29.The gear 29, like the gear 26, is free to rotate upon the shaft 21 andinterengages with a gear 30 also normally free to rotate upon the shaft18. The gear 26 intergears with the gear 31, likewise normally free torotate upon the shaft 21.

The clutch 24 is actuated by a yoke 32 carried by the lever 33, and theclutch 27 is actuated by a like yoke 34 actuated by the lever 35. Tocontrol the lovers 33 and 35 a lever 36 is provided pivotally connectedwith the housing 17 at 37 as shown more particularly at Figs. 1 and 3,and having pivotal. connection with such levers 33 and 35 at 38. It isobvious that when the lever 36 is moved in the direction of the arrowshown at Fig. 3 the levers 33 and 35 will be actuated to throw theclutch members 24 and 27 into engagement with the clutch faces 25 and 28whereby the gears 26 and 29 will rotate with the shafts 18 and 21respectively. The lever 36 is actuated in any approved manner when thebottom cone drops as by providing an arm 39 carrying a roller 40 which,when the cone drops, engages the cam 41 to move the lever 36 in thedirection indicated by the arrow. When, however, the cone drops it isthe result of the breaking of the belt 15, and shaft 13 ceases to beoperated from the lower cone 11. Provision is therefore made for drivingthe shaft 21 from the shaft 18 when the clutches 24 and 27 are throwninto engagement. This engaging means is controlled from the cone rack 16which is provided with an abutment 42 engaging a lever 43 pivotallyconnected with the housing in any approved manner as by the use of thearm 44 terminating in the stud 45 upon which is mounted the cam 46rigidly connected to and oscillating with the lever 43. Below andengaging with the cam 46 is a plunger 47 slidably inserted through thebrace 48 and pivotally connected with the walking beam 49 which is inturn pivotally connected with the housing 17 in any approved manner asby the link 50. A spring 51 is employed to normally hold the plunger 47yieldingly in engagement with the periphery of the cam 46.

Connected with the walking beam 49 at its end opposite the plunger 47 isa rod 52 passing upwardly through the housing 17 and integral with orrigidly connected to the sliding frame 53.

The sliding frame 53 carries yokes 54 and 55 engaging respectively theclutch members 56 and 57 which are respectively splined upon and movablelongitudinally of the shafts 18 and 21. The clutch members 56 and 57 arerespectively adapted to engage with the clutch faces 58 and 59 integralwith or rigidly connected to the gears 30 and 31 respectively. The cam46 is provided with springs 60 and 61 which are positioned to engageagainst the plunger 47 when the abutment 42 passes over the end of thelever.

43 and to throw such lever back into position for engagement by theabutment when the cone rack moves in the opposite direction as indicatedmore particularly at Fig. 4.

It will therefore be apparent that as the cone rack 16 reciprocates, thelever 43 is oscillated upon its pivot 45, and through the connectionabove described causes the sliding frame 53 and the clutch members 56and 57 to reciprocate to bring such clutch mem bers 56 and 57alternately into engagement with the clutch faces 58 and 59. As shown atFig. 2, all of the clutches are in neutral position, but at eachreciprocation of the cone rack the speed change clutches are caused toengage, but as the drive clutches are out of engagement the only resultis a difference in the rotation of the several gears which, however, isnot transmitted to the shaft 21. The position of the abutment 42 uponthe cone rack 16 is such that the speed is changed when the cone belt 15is substantially at the middle of its travel, and the connecting gearingis such that when the drive clutches are'thrown into engagement thechange speed clutches are in position to drive the shaft 21 faster orslower according to the position of the sliding frame 53 which is inturn controlled by the position of the cone belt 15. If, therefore, thecone belt breaks when between the middle and larger end of the uppercone the clutch mechanism is thrown into'engagement upon high speed,whereas if the cone belt breaks when the belt is between the middle andsmaller end of the drive cone the clutch mechanism is thrown intoengagement at low speed. The speeds are intended to be so arranged thatwhen the drive clutches are thrown into engagement on high speed theshaft 21 will be driven substantially at the speed the lower cone isdriven when the belt is half-way between the center point of the drivecone and its larger end; that is to say, at substantially one-third itstravel from the larger to the smaller end, whereas ifthe cone beltbreaks when the cone belt is between the middle and the smaller end ofthe drive cone, the low speed rotates the shaft 13 at substantially thespeed of rotation when the belt is two-thirds its travel from the largerto the smaller end of the drive or upper cone. While the drive thusprovided varies somewhat from the actual speed at which the shaft 13would be driven by the cone drive, it corresponds sufficiently theretoto prevent snarling of the thread due to complete stopping of thewinding apparatus, such winding apparatus being continued in motion at aspeed nearly the equivalent of the cone drive until the whole machinecan be brought to a stop by the automatic stop. In explanation of thegearing shown at Fig. 2, it may be pointed out that when the driveclutches are thrown into position the gears 26 and 29 are rigidlyconnected with the shafts 18 and 21 respectively. When the gears are inposition for slow drive the sliding frame 53 is down and the clutch 56in engagement with the clutch 58, but the clutch 57 is out of engagementwith the clutch face The interengagement of the clutch 56 with theclutch 58 causes the gear 30 to rotate also with the shaft 18 and todrive the ear 29 which, by reason of the engagement of the clutch 27with the clutch 28, drives the shaft 21, but the gear 30 being smallerthan the gear 29 the shaft 21 is driven slower than the shaft 18.Suchdriving is permitted from the fact that the gear 31 is not nowconnected with the shaft 21 but is free to rotate thereon and althoughthe gear 26 rotates with the shaft 18 it has no effect upon the gear 31except to rotate it freely upon the shaft.

When the high speed is to be applied, the clutch 57 engages the clutchface 59, the clutch 56 58 being now out of engagement. The gear 26 beingdriven with the shaft 18 drives the gear 31 which, by reason of theclutch engagement, is rigidly connected with the shaft 21 so that theshaft 21 is driven from the large gear 26 upon the drive shaft, thesmall gear 31 upon the driven shaft, thereby rotating the shaft 21 tohigher speed, this being permitted. from the fact that the gear is freeto rotate with the shaft 21 since the gear 30 is free to rotate on shaft18. As the sliding frame reciprocates at each reciprocation of the conerack, it follows that the gear is in position to pick up at fast or slowspeed according to the position of the cone belt whenever such cone beltbreaks, and owing to the fact that the machinery is all in motion thereis comparatively little strain upon the pick-up owing to such breakage.

I claim:

1. The combination with a speeder involving a cone drive, of clutchmechanism con nected ,with the opposite sides of such drive, means toshift the clutch mechanism from high to low speed at each reciprocationof the cone belt, and means to throw the clutch mechanism into operationwhen the lower cone drops.

2. The combination with a speeder involving a cone drive, of shaftsintergeared with the upper and lower cone drive mechanism, gears carriedby the shafts normally free to rotate upon such shafts, speed changemechanism, means to actuate the speed change mechanism from thereciprocation of the cone rack, clutches adapted to connect the gearingwith the shafts, and means actuated when the lower cone drops to throwsuch last-named clutches into engagement.

8. The combination with a speeder involving a cone drive, of shaftsintergeared with the top cone driving mechanism and with the mechanismdriven by the bottom cone respectively, intergeared gearing carried bythe shafts and normally free to rotate thereon, speed changing mechanismactuated from the cone rack, clutches adapted to connect the gearingw'th the shafts, a lever adapted to actuate the clutches, and meanscarried by the lower cone for actuating the lever when the cone drops.

l. The combination with a speeder involving a cone drive, of normallyinactive gearing interposed between the cones, means to change the speedconnection to correspond approximately with the speed change of the conedrive, and means to throw the normally inactive gearing into action todrive the mechanism when the cone belt breaks.

In testimony whereof I affix my signature.
